The EV4068-S-00A Evaluation Board is designed to demonstrate the capabilities of MP4068. The MP4068 is a highly integrated TRIAC dimmable LED driver with high power factor. It is specifically designed for low-line input (120VAC), no-isolated, TRIAC-dimmable LED lighting applications, especially for the low cost and small form factor applications.
The integrated 500V MOSFET ensures the system to withstand 500V surge test without MOV or TVS. Only a single winding inductor is required to realize the solution. It features MPS’s proprietary hybrid operation mode which is designed to achieve good dimming performance.The EV4068-S-00A is typically designed for driving an 7W Triac dimmable LED bulb with 50VTYP, 140mA LED load from 108VAC to 132VAC, 60Hz.
The EV4068-S-00A has an excellent efficiency and meets IEC61547 surge immunity, IEC61000-3-2 Class C harmonics and EN55015 conducted EMI requirements. It has multi-protection function as over-voltage protection; output short-circuit protection, thermal shut down, etc.

The MP4068 is a highly integrated TRIAC dimmable LED driver with a high power factor (PF). It precisely can output regulates precisely an accurate LED current for ain non-isolated lighting applications., Onlywith a single winding inductor is required to realize the solution. For low-line (120VAC) applications, tThe integrated 500V MOSFET can make sure ensures that the system canto withstand a pass 500V surge test without MOV or TVS for low line input application. The It features MPSs proprietary hybrid operation mode, which is designed to to get a achieve good dimming performance. The MP4068 is specifically designed specifically for low- line input (120VAC), and TRIAC -dimmable LED lighting applications, especially for the low cost and small form factor applications. The accurate output LED current is achieved by an internal averaging current feedback loop. An internal high- voltage regulator makes the MP4068 start-up quickly without a perceptible delay. The power de-rating at high temperature makes the system flicker-free when the ambient temperature is high. The MP4068 has features various protection featuress like such as VCC UnderuUnder- vVoltage lLockout (UVLO), oOver- vVoltage pProtection (OVP), and sShort- cCircuit pProtection (SCP). All of these features make MP4068 an ideal solution for simple, off-line, and non-isolated TRIAC dimmable LED lighting applications. The MP4068 is available inn the TSOT23-5 and SOIC8-7A and SOIC-8 -EP packages.
